skip method

Returns a stream that emits the same events as this stream would
if listened to at the same time, except that the first count
data events are not emitted.
The returned stream is done when this stream is.

If this stream emits fewer than count data events
before being done, the returned stream emits no data events.

The returned stream is a broadcast stream if this stream is.
For a broadcast stream, the events are only counted from the time
the returned stream is listened to.
